Papilio nephelus is a species of swallowtail butterfly belonging to the family Papilionidae. Subspecies include P. n. chaon, the yellow Helen, and P. n. sunatus, the black and white Helen.
Papilio nephelus has a wingspan reaching about 10–12 centimetres (3.9–4.7 in). The basic colour of the wings is black, with a chain of white spots on the forewing and a large white or yellow area on the hindwing. The underside and the upperside of the wings in this species are very similar. The hindwings have wavy margins, with long tails. The thorax and the abdomen are black. [2]
Papilio nephelus superficially closely resembles P. helenus . The differences are, however, both of structure and of colour. Male forewing upperside: entirely without the thick coating of short hairs on the outer half. Upperside: black with a sprinkling of yellowish-brown scales on the forewing, that form four longitudinal streaks on the cell and internervular streaks on the outer half. Hindwing: the upper discal white patch larger, formed of elongate broad streaks in interspaces 4 to 7 (not 5 to 7): no tornal nor subterminal markings. Underside ground colour duller brownish black; forewing with the diffuse scaling so disposed as to form grey cellular and internervular streaks, the streaks in interspaces 1a and 1 generally white, not diffuse. Hindwing: basal area sprinkled with yellow scales that form three longitudinal slender lines in the cell: the upper white discal patch as on the upperside, but the elongate white markings that compose it well divided by the black veins; below the discal white patch there is a small series of white spots in interspaces 1 to 3, the spot in 1 generally, in 2 very often, tinged with ochraceous yellow; a subterminal complete series of ochraceous-yellow lunules followed by admarginal narrow white spots. Antennae, head, thorax, and abdomen black; beneath: a line of white on the palpi, the thorax with some linear white markings.
Female similar. Upperside ground colour browner; forewing: cellular and internervular streaks more prominent; in many specimens an obscure diffuse whitish subcostal shading just beyond apex of coll. Underside paler. Forewing with the cellular and internervular streaks and subcostal postcellular whitish patch more prominent; the posterior three internervular short streaks on the outer half of the wing white, not diffuse; in a few specimens there is a series of more or less conspicuous admarginal white spots, one in the middle of each interspace. Hindwing markings similar to those in the male, but larger and more prominent. Antennae, head, thorax, and abdomen as in the male, but the abdomen beneath with lateral white markings. [3]
Larvae feed on Toddalia asiatica , Euodia meliifolia , Fagra rhetsa , Citrus species and Zanthoxylum rhetsa . [4]
This species can be found the Asian part of the Palaearctic realm and partially in the Australasian realm and in the Indomalayan realm, from Nepal, Sikkim, Assam, to the south of China, and from Myanmar to Thailand, Cambodia and Indonesia. [2] [4]
These butterflies are mainly present in the lowlands in the primary forests.

Though not uncommon, it is protected under Indian law under the name gyas.
Papilio clytia, the common mime, is a swallowtail butterfly found in south and southeast Asia. The butterfly belongs to the subgenus Chilasa, the black-bodied swallowtails. It serves as an excellent example of a Batesian mimic among the Indian butterflies.
Papilio (Chilasa) epycides, the lesser mime, is a swallowtail butterfly found in India and parts of South-East Asia. The butterfly belongs to the mime (Chilasa) subgenus or the black-bodied swallowtails. It is a mimic of a common Indian Danainae, the glassy tiger butterfly.
Papilio (Chilasa) paradoxa, the great blue mime, is a swallowtail butterfly found in India and parts of South-East Asia. The butterfly belongs to the mime subgenus, Chilasa, of the genus Papilio. It is an excellent mimic of different species of Euploea.
Papilio (Chilasa) slateri, the blue striped mime, is a swallowtail butterfly found across south and south-east Asia. The butterfly belongs to the mime subgenus, Chilasa, of the genus Papilio, the black-bodied swallowtails. The nominate subspecies is found in India and is also called the brown mime. It is a good example of mimicry among Indian butterflies.
Papilio mayo, the Andaman Mormon, is a species of swallowtail butterfly that is endemic to the Andamans in the Bay of Bengal. It is a species that is protected by Indian Law. The scientific name honours Richard Bourke, 6th Earl of Mayo, who was assassinated at Port Blair the year before the butterfly was discovered.
